初一語法也就這么多了.
初一英語語法雖然是從簡單的一些日常用語出發(fā)的,但語法中常會(huì)有一些知識(shí)點(diǎn)看起來很細(xì)小,容易被忽視,但這些知識(shí)點(diǎn)掌握不熟練,往往會(huì)造成一些語法應(yīng)用上的錯(cuò)誤.因此在學(xué)習(xí)初一英語語法時(shí),要認(rèn)真、細(xì)心,不要覺得一些地方不重要而得過且過.
下面從幾個(gè)方面,總結(jié)出了初一英語語法,如果要復(fù)習(xí)英語句法的同學(xué),可以參考一下,
一、初一英語語法——詞法
1、名詞
A）、名詞的數(shù)
我們知道名詞可以分為可數(shù)名詞和不可數(shù)名詞,而不可數(shù)名詞它沒有復(fù)數(shù)形式,但可數(shù)名詞卻有單數(shù)和復(fù)數(shù)之分,復(fù)數(shù)的構(gòu)成如下：
一）在后面加s.如：fathers, books, Americans, Germans, apples, bananas
二）x, sh, ch, s, tch后加es.如：boxes, glasses, dresses, watches, wishes, faxes
三）1）以輔音字母加y結(jié)尾的變y為i再加es 如：baby-babies, family-families, duty-duties, comedy-comedies, documentary-documentaries, story-stories
2）以元音字母加y結(jié)尾的直接加s.如：day-days, boy-boys, toy-toys, key-keys, ways
四）以o結(jié)尾加s（外來詞）.如：radios, photos, 但如是輔音加o的加es：如: tomatoes西紅柿, potatoes馬鈴薯
五）以f或fe結(jié)尾的變f為v再加es(s).如：knife-knives, wife-wives, half-halves, shelf-shelves, leaf-leaves, yourself-yourselves
六）單復(fù)數(shù)相同（不變的）有：fish, sheep, deer鹿子, Chinese, Japanese
七）一般只有復(fù)數(shù),沒有單數(shù)的有：people,pants, shorts, shoes, glasses, gloves, clothes, socks
八）單詞形式不變,既可以是單數(shù)也可以是復(fù)數(shù)的有：police警察局,警察, class班,同學(xué), family家,家庭成員
九）合成的復(fù)數(shù)一般只加主要名詞,多數(shù)為后一個(gè)單詞.如：action movie-action movies, pen pal-pen pals; 但如果是由man或woman所組成的合成詞的復(fù)數(shù)則同時(shí)為復(fù)數(shù).如：man doctor-men doctors, woman teacher-women teachers
十）有的單復(fù)數(shù)意思不同.如：fish魚 fishes魚的種類, paper紙 papers報(bào)紙,卷子,論文, work工作 works作品,工廠, glass玻璃 glasses玻璃杯,眼鏡, orange桔子水 oranges橙子, light光線 lights燈, people人 peoples民族, time時(shí)間 times時(shí)代, 次數(shù), chicken 雞肉 chickens 小雞
十一） 單個(gè)字母的復(fù)數(shù)可以有兩種形式直接加s或’s.如：Is (I’s), Ks (K’s).但如是縮略詞則只加s.如：IDs, VCDs, SARs
十二） 特殊形式的有：child-children, man-men, woman-women, foot-feet, mouse-mice, policeman-policemen, Englishman-Englishmen
B）名詞的格
當(dāng)我們要表示某人的什么東西或人時(shí),我們就要使用所有格形式.構(gòu)成如下：
一）單數(shù)在后面加’s.如：brother’s, Mike’s, teacher’s
二）復(fù)數(shù)以s結(jié)尾的直接在s后加’,如果不是以s結(jié)尾的與單數(shù)一樣處理.如：Teachers’ Day教師節(jié), classmates’; Children’s Day六一節(jié), Women’s Day三八節(jié)
三）由and并列的名詞所有時(shí),如果是共同所有同一人或物時(shí),只加最后一個(gè)’s,但分別擁有時(shí)卻分別按單數(shù)形式處理.如：Mike and Ben’s room邁克和本的房間（共住一間）,Mike’s and Ben’s rooms邁克和本的房間（各自的房間）
2、代詞
項(xiàng)目 人稱代詞 物主代詞 指示代詞 反身代詞
人稱 主格 賓格 形容詞 名詞性
第一人稱 單數(shù) I me my mine myself
復(fù)數(shù) we us our ours ourselves
第二人稱 單數(shù) you you your yours yourself
復(fù)數(shù) you you your yours yourselves
第三人稱 單數(shù) she her her hers herself
he him his his himself
it it its its this that itself
復(fù)數(shù) they them their theirs these those themselves
3、動(dòng)詞
A） 第三人稱單數(shù)
當(dāng)動(dòng)詞是第三人稱單數(shù)時(shí),動(dòng)詞應(yīng)該像名詞的單數(shù)變動(dòng)詞那樣加s,如下：
一）一般在詞后加s.如：comes, spells, waits, talks, sees, dances, trains
二）在x, sh, ch, s, tch后加es.如：watches, washes, wishes, finishes
三）1）以輔音字母加y結(jié)尾的變y為i再加es.如：study-studies, hurry-hurries, try-tries
2）以元音字母加y結(jié)尾的直接加s.如：plays, says, stays, enjoys, buys
四）以o結(jié)尾加es.如：does, goes
五）特殊的有：are-is, have-has
B） 現(xiàn)在分詞
當(dāng)我們說某人正在做什么事時(shí),動(dòng)詞要使用分詞形式,不能用原形,構(gòu)成如下：
一）一般在后加ing.如：spell-spelling, sing-singing, see-seeing, train-training, play-playing, hurry-hurrying, watch-watching, go-going, do-doing
二）以不發(fā)音e的結(jié)尾的去掉e再加ing.如：dance-dancing, wake-waking, take-taking, practice-practicing, write-writing, have-having
三）以重讀閉音節(jié)結(jié)尾且一個(gè)元音字母＋一個(gè)輔音字母（注意除開字母組合如show –showing, draw-drawing）要雙寫最后的輔音字母再加ing.如：put-putting, run-running, get-getting, let-letting, begin-beginning
四）以ie結(jié)尾的變ie為y再加ing.如：tie-tying系 die-dying死 lie-lying 位于
4、形容詞的級
我們在對兩個(gè)或以上的人或物進(jìn)行對比時(shí),則要使用比較或最高級形式.構(gòu)成如下：
一） 一般在詞后加er或est(如果是以e結(jié)尾則直接加r或st).如：greater-greatest, shorter –shortest, taller –tallest, longer –longest, nicer- nicest, larger -largest
二）以重讀閉音節(jié)結(jié)尾且1個(gè)元音字母＋1個(gè)輔音字母(字母組合除外,如few-fewer fewest)結(jié)尾的雙寫結(jié)尾的輔音再加er /est.如：big-bigger biggest, red-redder reddest, hot-hotter hottest
三） 以輔音字母＋y結(jié)尾的變y為i加er/est.如：happy-happier happiest, sorry-sorrier sorriest, friendly-friendlier friendliest(more friendly most friendly), busy-busier busiest, easy-easier easiest
四）特殊情況：(兩好多壞,一少老遠(yuǎn))
good/well - better best many/much - more most bad/ill – worse worst
little- less least old- older/elder oldest/eldest far- farther/further farthest/furthest
5、數(shù)詞 (基變序,有規(guī)則；一、二、三,自己背；五、八、九、十二；其它后接th；y結(jié)尾,變?yōu)閕, eth跟上去.) first, second, third; fifth, eighth, ninth, twelfth; seventh, tenth, thirteenth, hundredth; twenty-twentieth, forty-fortieth, ninety-ninetieth
